1Binding for the CPLD LEDs (GPIO extension bus) found on some LaCie/Seagate
2boards (Example: 2Big/5Big Network v2, 2Big NAS).
3
4Required properties:
5- compatible: "lacie,netxbig-leds".
6- gpio-ext: Phandle for the gpio-ext bus.
7
8Optional properties:
9- timers: Timer array. Each timer entry is represented by three integers:
10  Mode (gpio-ext bus), delay_on and delay_off.
11
12Each LED is represented as a sub-node of the netxbig-leds device.
13
14Required sub-node properties:
15- mode-addr: Mode register address on gpio-ext bus.
16- mode-val: Mode to value mapping. Each entry is represented by two integers:
17  A mode and the corresponding value on the gpio-ext bus.
18- bright-addr: Brightness register address on gpio-ext bus.
19- max-brightness: Maximum brightness value.
20
21Optional sub-node properties:
22- label: Name for this LED. If omitted, the label is taken from the node name.
23- linux,default-trigger: Trigger assigned to the LED.
